Please help me find something to wear

[AtSea1979]

I'm tall and overweight and feeling very unattractive. I live in jeans and tshirt and even just wearing a dress makes me feel anxious. I have an afternoon at the races planned but no idea what to wear, I don't want to go to formal (it's not ladies day) but need something a little dressy. As for shoes, I'm even worse as I'm size 9 and don't tend to wear heels as I'm tall enough. Also don't wear open toes as I had my toe nails removed so paranoid about them.

Saw some nice floaty summery trouser suits in debenhams recently

Not to sure what u mean, could you link me one?

Can I ask how tall and how overweight? Not being horrid - I'm 5'10" and was a size 20 so I have some experience!

Shoe-wise, how about bright pointed flats?

I'm 5'10" and a size 16

I love this monsoon top, looks much better IRL than on the model, hangs well and flattering. It is quite spangly so would be good with very dark, straight jeans if you want a 'jeans and t shirt' feel but smarter?

Oh that's pretty, I don't usually wear tops that short but it would hide the muffin top well, I might get that one anyway but I think jeans are banned in my area.
I went to Next today but they had nothing. I think I'll wear a dress but want to find one I'll feel comfortable in.
